Process for the Recovery of Precious Metal from an ore or Concentrate of Sulfur or other material Feeding, a method to Suppress and to minimise the formation of thiocyanate for the Recovery of Precious Metal and a method for reducing the formation of Copper cyanide
1. The process of extracting precious metals such as gold or silver or other source materials from ore or concentrate, including placing raw materials under oxidation pressure to produce oxidation. The pressure oxidation suspension combusts downward when the temperature and pressure decrease, and then carries on the liquid or the solid separation.A high-pressure oxidation solution and a solid residue are used to connect precious metals. The solid residue is then cyanidated to extract the precious metal. Thiocyanate formation during cyanidation is minimised or offset by cyanidation at high oxygen pressure and by reducing retentionAbout 30 to 90 minutes A method for reducing the formation of copper cyanide in the process of cyanide leaching is also provided.
